Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529036, here are decompositions:
- 43 + 31528993 = 31529036
- 67 + 31528969 = 31529036
- 127 + 31528909 = 31529036
- 193 + 31528843 = 31529036
- 223 + 31528813 = 31529036
- 229 + 31528807 = 31529036
- 307 + 31528729 = 31529036
- 313 + 31528723 = 31529036
Showing the first eight; more decompositions exist.
